Hardware Compatibility

Hardware Reported to Work

The following list is compiled by the unRAID user community. While it is mostly accurate, it is not definitively so, as it cannot be guaranteed that users have the time, expertise or diligence to test and report back all aspects. It is recommended that if you are using this list, you do so in conjunction with heavy use of the forum.

  • Although boards are listed here by name, compatibility is actually determined by the Linux kernel with the chipsets onboard. Chipset info may not be listed for all boards yet. But if you are looking at a board that is not listed here, check to see what are its major chipsets (Northbridge, Southbridge, network controller, disk controller(s)), and if they are listed below, or are on boards that are listed, then the chances are very good that the board is fully compatible.
  • A voluminous source of motherboard specs is here, on the AVS forums, commented on here.
  • Users are starting to add motherboard info with compatibility grades to the Personal Text field of their forum posts, which appears on the left side of the post, under the post count. For more information, see this thread. Wondering how to add this info? See this post.
  • Also check user sigs (signatures) within the forums for motherboard and other build information. Their actual build may be listed, or a link entitled My Rig which should take you to detail about their system. And check the Pimp Your Rig forum thread for user builds with pictures.
  • All unRAID users are invited to add their working boards here, to help others. We recommend you also add a new topic to the Motherboards forum, with your board as Subject heading, and listing more details of your build. Others are especially interested in the CPU and RAM choices you have found to work, as well as your power supply, CPU cooler, fans, addon disk controllers, disk drives, case, etc. Additional links to the manufacturer's product page and a mainstream vendor's product page are always appreciated too. And any special build tips or BIOS settings changes are always helpful.


An explanation of what the "Tested Level" column means

  • The first level should require at least 3 drives (limit of free license), should have successfully computed parity, and should have successfully checked parity. A syslog should be posted to make sure there are no nasties that might point to compatibility issues. (The syslog will also document parity check performance).
  • The second level should be a user with at least 6 drives (limit of Plus license) that has run for a month without a power down, had a successful parity check at the beginning and end of the month. A syslog should be posted here for that period. During this period at least 10% of the array size should be copied to and from the array.
  • The third level would be a user that has had 13+ drives (including a cache disk), that has run for two months without a power down, has successfully parity checked at least 3 times (start, middle, end) and has posted a good syslog for that period. During this period at least 15% of array size should be copied to and from the array.

The syslog(s) will provide some evidence of good functionality, and running the parity checks will establish good habits going forward. Those looking to make purchase decisions will have more to go on than a casual statement of "it works perfect."


When verification is received that a given board has passed the outlined level a check mark (✓) will be added and a link back to the thread as proof of the completion.



IMPORTANT! The boards listed here have been added by users like you. They were found to work with their specific set of drives, addon controllers, CPU, and RAM, and are not guaranteed in any way to work with other controllers, CPU, and RAM. They very likely have not tested all features of the board, so it is possible that a board listed here as compatible, will not prove compatible with your hardware. As negative reports come in, they will be added to this list.



Motherboard

The motherboard is probably the biggest and most important decision that you will make. There are 3 ways to go:

  • use a board you already have - need to confirm its compatibility - likely to be older and slower with few SATA ports
  • study the Motherboard forum, watch for sales, check this page - and select the board that seems best for you - unRAID has very good compatibility with most boards
  • select one of the 'official' boards (Asus P5B-VM DO and Super Micro C2SEE), used by Lime Technology itself in its pre-built systems for purchase - maximum compatibility because tested the most by the developer - recommended by several veteran unRAID users, here's why - 'official' boards are clearly marked below

Here are some additional thoughts on the 4 classes of motherboards, from well-tested to untested.

NOTE: If you own or are considering a Gigabyte board, you need to be aware of the HPA issue. If it is possible, it is highly recommended to update to the latest BIOS of your Gigabyte board and disable the option to backup the BIOS to the hard drive.

Processor

  • Any; 2.0GHz or higher is recommended, but many users are happy with 1.6GHz, at least one was fine with a 1.2GHz CPU; [2], [3]
  • Single and multiple core processors are fine. As of unRAID v4.4, multiple core processors are fully supported. For versions of unRAID through v4.3.3, multiple core processors work fine, but only one processor is used.


Memory

  • Minimum 512MB, maximum 64GB


  • Maximum was 1GB - prior to Version 4.3-beta6
  • Maximum was 4GB - prior to Version 4.4-final


  • Recommend 2 equal sticks of 512MB or 1GB or 2GB in order to run in dual-channel mode; speed matched to the FSB of your CPU.

unRAID will run in 512MB just fine for normal serving of media files. If you plan on running add-on applications that use a lot of memory, 1GB, 2GB, or more, is better.

USB Flash Drives

The unRAID server software boots from a USB flash drive, 128MB or larger. If you plan on enhancing your unRAID server with addons, then 512MB or larger is recommended. If you think you may want to build your own custom Linux kernel, then 1GB or larger is recommended.

To use the free Basic version of unRAID, no GUID is required. To use a registered copy of unRAID, whether the Plus or Pro version, the flash drive must have a valid GUID. A GUID is like a product serial number, but does not actually exist on the flash drive. It is constructed by the Linux kernel from the flash drive's manufacturer, product ID, and internal serial number. The foolproof way to check if your device has a usable GUID, is to download the UnRAID software, extract it to your flash drive (USB Flash Drive Preparation), boot unRAID in a test machine, go to the Web Management page (top of the UnRAID Manual), and just select/copy/paste the GUID from the Devices tab. If the last 12 characters of your Flash GUID are all zeros, then it does **not** have a serial number and you can **not** register it. You can also utilize a Microsoft utility UVCView.mspx from within Windows to determine the USB device's GUID (which consists of idVendor+idProduct+0000+iSerialNumber), but this is unofficial, and should not be used for registration.

  • Note: Lime Technology strongly recommends you obtain your Flash GUID via the Devices page. This not only ensures the correct GUID, but also that your hardware platform can boot from Flash and run the unRAID OS.

Recommended Builds

(Current as of April 7th, 2010)

Budget Box

United States Version

All of the following components are available through online retailers in the United States. All prices are in USD. Inspired by LimeTech's own RB-1200
Recommended retailers:

  • Newegg (there's really no reason to shop anywhere else unless you find an item on sale elsewhere)
  • TigerDirect
  • Amazon (if you are desperate, their shipping is pretty bad)


Components:

  • CPU: 2.7 GHz AMD Sempron 140
  • Motherboard: BIOSTAR A760G M2+
    • The Biostar A760G M2+ motherboard is currently hard to find or unavailable. We are working on an alternative. See this thread for details.
  • RAM: Kingston 2 GB DDR2 800 RAM (Pretty much any DDR2 800 RAM will do, just get at least 1 GB on a single stick. 1 GB is sufficient for stock unRAID usage, get 2 GB or more if you plan on using add-ons)
  • Power Supply: CORSAIR Builder Series CX430 CMPSU-430CX (will support up to 12 low power/green drives)
  • Case: Cooler Master Centurion 590 - *Same hardware used by LimeTech*
  • Hard Drive Bays:
    • Hot Swap - ICY DOCK MB454SPF-B Multi-Bay Backplane Module (4-in-3) - *Same hardware used by LimeTech*
      • The recommended case will support up to 3 of these units, for a total of 12 drives.
    • Non-Hot Swap - COOLER MASTER STB-3T4-E3-GP 4-in-3 Device Module Hardisk Cage
      • The recommended case will support up to 3 of these units, for a total of 12 drives. However, the case comes with an internal 4-in-3 hard drive cage, so only two of these units would be necessary to achieve a 12 drive capacity.
    • Note on hot swap bays: Many computer cases including the recommended CM-590 have metal tabs separating each 5.25" drive bay. Many hot swap drive cages do not accommodate these metal tabs. Most unRAID server builders just use a pair of pliers and a small hammer to bend/flatten these tabs out of the way. However, if you do not want to bother with this type of case modification, then you should shop for a hot swap hard drive cage that does accommodate these tabs, such as the SNT-3141 SATA-II Hot-Swap 4 Drive Enclosure.
  • Expansion Card: Supermicro Add-on Card AOC-SASLP-MV8 - *Same hardware used by LimeTech*
    • Only required if support for 7 - 12 drives is desired
    • Also requires two breakout cables
  • Hard Drives: The capacity and speed of the hard drives you choose will vary depending on your server's purpose, but here are some 2 TB drives to choose from:
    • 2 TB Seagate Barracuda LP
    • 2 TB Samsung Spinpoint F3EG
    • 2 TB WD Green EARS
      • Note: On the WD EARS drive, you will need to install a jumper on pins 7-8 on this drive before installing it in your unRAID server.
    • It is best practice to avoid buying multiple drives from the same manufacturer at the same time. Doing so increases your risk of a multiple drive failure, a situation from which unRAID cannot recover.

At current prices (as of March 29, 2010), the above configuration totals:

  • $730 + Shipping + Cost of Hard Drives (With 12 Hot Swap Bays, supports up to 12 drives)
  • $455 + Shipping + Cost of Hard Drives (With 12 Non-Hot Swap Bays, supports up to 12 drives)
  • $300 + Shipping + Cost of Hard Drives (With 4 Non-Hot Swap Bays + 2 Internal, supports up to 6 drives)
  • $275 + Shipping + Cost of Hard Drives (With 4 Internal Non-Hot Swap Bays, supports up to 4 drives)

Always check the Good Deals Forum for current sales.

For some pictures of Budget Boxes in action, see kizer's server, kansur's server, and guiri's server. Note that none of these use the exact configuration listed above, but all are very similar.

First Time Configuration

This section covers how to configure your new Budget Box (US Version using the Biostar A760G M2+ motherboard) the first time you boot it up. You should follow the steps in the order below, otherwise this may not work properly.

  • First of all, make sure all your WD EARS (and any other advanced format drives) have jumpers installed before booting your server!
  • Prepare your USB Flash drive for unRAID as described in the instructions here. Your bootable flash drive must be plugged into the server before the rest of this will work.
  • As your server boots for the first time, press and hold the 'Delete' key to enter BIOS setup. In BIOS, use the arrow keys to navigate and make changes and the enter key to select items. Hit Escape to go back a screen. Make the following changes in the order shown here:
    • On the Chipset tab
      • Choose 'Southbridge Configuration'
        • Set the OnChip SATA Type to AHCI
        • Disable SATA IDE Combined Mode
    • On the Advanced tab
      • Choose 'USB Configuration'
        • Choose 'USB Mass Storage Device Configuration'
          • Set the Emulation Type to Hard Disk
    • On the Boot tab
      • Choose 'Hard Disk Drives'
        • Choose '1st Drive', select the USB Flash drive, and press enter
        • Disable all other boot drives
      • Choose 'Boot Device Priority'
        • Set the 1st Boot Device as the USB Flash drive.
        • Disable all other boot devices
  • Finally, press F10 to save your changes and reboot the server. The next time you turn on your server it should boot into unRAID automatically.

Australia Version

All of the following components are available through online and brick and mortar retailers in Australia. All prices are in AUD.
Recommended retailers:


Components:

  • CPU: 2.7 GHz AMD Sempron 140
  • Motherboard: Asus M4A785T-M
  • RAM: Kingston 2 GB DDR3 1333 RAM or Kingston 1 GB DDR3 1333 RAM (1 GB is sufficient for stock unRAID usage, get 2 GB or more if you plan on using add-ons)
  • Power Supply: Corsair CX-400 400W (will support up to 12 drives)
  • Case: Antec Three Hundred
  • Hard Drive Bays:
    • Hot Swap - SNT-3141 SATA-II Hot-Swap 4 Drive RAID Enclosure (eBay price: $120 each)
      • You can forgo this option as the case only allows for one of these. To keep things on a budget scale, I'd suspect most would build this server without them and would use the Cooler Master STB-3T4-E3-GP 4-in-3 Device Module Hard disk Cage.
    • Non-Hot Swap - Cooler Master STB-3T4-E3-GP 4-in-3 Device Module Hard disk Cage (eBay price: $40, would only need one for this case)
  • Expansion Card: If you plan to use more than 6 SATA drives, you'll need to buy a compatible SATA RAID controller ($40 gets you a 4 Port SATA I RAID controller, about $70 gets you a 4 PATA II RAID Controller. PCIe would retail for about $100+ 4 Port card).
  • Hard Drives:

At current prices (as of April 3, 2010), the above configuration totals:

  • $352.90 + hard drives (base system, non-hot swap bays, 1 GB of RAM)
  • $464.80 + hard drives (baller system, hot-swap bays, 2 GB of RAM)

Always check the Good Deals Forum for current sales.


UK Version

    • The recommended motherboard can support up to two of these expansion cards, one in each PCIe slot.
    • Two of these cards are required for full 20 drive support.
    • Separate SAS or SAS to SATA breakout cables are required.
      • Use a SFF-8087 to SFF-8087 SAS cable to connect the Norco 4220's internal SAS backplanes to the Supermicro AOC-SASLP-MV8 (you will need two cables per card, since each cable supports up to 4 hard drives)
      • Use a SFF-8087 Reverse (SFF8087OCR) SAS cable to connect the Norco 4220's internal SAS backplanes to the motherboard's onboard SATA slots (again, each cable supports 4 drives).
  • Power Supply: CORSAIR CMPSU-650TX
    • Supports 20+ drives, but it is recommended that you use primarily green drives to keep power consumption low.
  • Case: Norco 4220
    • Includes 20 Hot Swap hard drive bays (each bay has a tray, they are not trayless)
    • Often bundled with something nice, such as a free hard drive or a free motherboard

At current prices (as of 9/1/2010), the above configuration totals:

  • $940 + Shipping + Cost of Hard Drives (With 20 Hot Swap Bays, supports up to 20 drives)

Always check the Good Deals Forum for current sales.


5 Drive miniBox

  • CPU: 2.7 GHz AMD Sempron 140
  • Motherboard: BIOSTAR A760G M2+
    • The Biostar A760G M2+ motherboard is currently hard to find or unavailable. We are working on an alternative. See this thread for details.
  • RAM: Kingston 2 GB DDR2 800 RAM (Pretty much any DDR2 800 RAM will do, just get at least 1 GB on a single stick. 1 GB is sufficient for stock unRAID usage, get 2 GB or more if you plan on using add-ons)
  • Power Supply: CORSAIR CMPSU-400CX 400W (will support up to 12 low power/green drives)
  • Case: Rosewill R101-P-BK
    • Chosen for value, not style
    • You may need to flatten the small tabs that separate the 5.25" bays depending on the 5-in-3 cage you choose.
  • Hot Swap Hard Drive Bays: - ICY DOCK MB455SPF-B Multi-Bay Backplane Module
  • Hard Drives: The capacity and speed of the hard drives you choose will vary depending on your server's purpose, but here are some 2 TB drives to choose from:
    • 2 TB Seagate Barracuda LP
    • 2 TB Samsung Spinpoint F3EG
    • 2 TB WD Green EARS
      • Note: On the WD EARS drive, you will need to install a jumper on pins 7-8 on this drive before installing it in your unRAID server.
    • It is best practice to avoid buying multiple drives from the same manufacturer at the same time. Doing so increases your risk of a multiple drive failure, a situation from which unRAID cannot recover.

At current prices (as of 8/16/2010), the above configuration totals:

  • $350 + Shipping + Cost of Hard Drives (With 5 Hot Swap Bays, supports up to 5 drives)

Always check the Good Deals Forum for current sales.

For an example of the miniBox in action, see this thread. Note that I do not recommend the hot swap drive cage I used there as it does not have very good airflow.

Hardware Known to NOT Work

USB Flash Drives

  • Verbatim Store'n'Go Professional. Strange problems with the key being recognized, but not automounted during boot.
  • Alien 1GB. Recognized but syslinux gives kernel linux not found error. No obvious fix, stay away.
  • SuperTalent Pico - these do work at first, but see Not For unRAID: SuperTalent Pico series Flash drives


Hard Disk Drives

  • Western Digital AAKS drives. Mixed reports (see here and here). In some scenarios spindown of these drives completely hangs unRAID, while numerous other users report success with them. Consider other options if buying new drives, and thoroughly test if using an existing AAKS drive in your array.


Motherboards / Processors

  • Motherboards based on the nForce2, nForce3, and nForce4 chipsets are not recommended. They are notorious for data corruption issues, IDE detection issues, and incompatibilities with certain hard drives. This can result in failures to boot, corrupted files, corrupted network transfers, inability to use certain drives, etc. Many owners of these boards have wasted many days trying to get reliable operation, without success, and there are a number of very long threads about these problems on the Internet. It is the opinion of some that the Asus A8N family of nForce4 boards are the only ones that may be safe to use, possibly because Asus was the only one to put a tremendous effort into putting workarounds for the problems into the BIOS. For further discussion and links for research, see this thread. Boards based on later nForce chipsets, from nForce5 and higher, are fine, although may require small workarounds to operate well, such as special boot options, if using versions of unRAID prior to v4.4 final. nForce boards are generally very good performers, with very good feature sets.
  • Had lengthy problem of parity errors with system of ECS P4M800PRO-M V2.0 motherboard, Intel Core2Duo E4300, & Trendnet Gigabit PCI LAN. Not sure which variable was the issue. Can reference thread http://lime-technology.com/forum/index.php?topic=2417. Note: motherboard chipsets are VIA P4M800 PRO and VIA VT8237R Plus


Other Hardware Recommendations

this section is still very incomplete

Cases


Drives

The recommended practice is to space out or stagger your hard drive purchases as much as possible, and to avoid buying multiple hard drives from the same manufacturer at the same time. Doing so increases your chance of a multiple drive failure from which unRAID cannot recover. Read more...
